To all whom it mag concern:

Be it known that I, ARTHUR EDWARD HoGUE, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Crushing-Rolls, of which the ollowing is the specification.

My invention relates to improvements in crushing rolls particularly adapted for ores,

and the object of the invention is to devise journaled on the bed plate between which r and rollers such cam wheel extends, a ho per su ported at the top by rollers on suital; e guide-ways journaled on'pins depending from the bottom of the hopper and abutting the 'minor roll as hereinafter more particularly ex lained.

' indicate corresponding igurel, is a plan view partially in section showing the hopper .in dotted lines. Fig. 2, is a sectional elevation' Fig. 3, is side view of a modification. Fig.- 4 is a plan view of Fig. 3.

In the drawings like letters of reference parts in each figure. A is the bed plate of themachine;

B is the shaft carrying the major roll C, such shaft being journaled in-suitable bearings B secured. to the bed late. I

D is the minor roll, whic is of less width than the major roll. The roll D is carried by a shaft D, which is journaled in suitable bearings D secured to the bed plate.

' 'E is a cam wheel, which is secured on one end of the shaft Dand has thefaces thereof designed to engage with-the friction. rolls F journaled on the pins G held in the-bed plate. \The volute of the cam is such that upon the rotation of the shaft a longitudinal reciprocating movement is imparted t o 1t, such shaft being driven by a suitable dI'IVIIlg pulley G as indicated. P

H is a chute connected to the hopper H. The hopper is provided at the top with brackets H in which are journaled the grooved rollers H which rest upon the guiding rods I. There are two rollers on Specification of Letters Patent. Application filed March 25, 1908.

eachside of the hopper as indicated by Patented June 8, 1909. I

J are pins depending from the chute or a lower portion of the hopper and having located thereon the friction rollers K.

L is a shaft provided with an emery wheel L, such emery wheel; being designed to true the surface of the periphery of the roller 0.

Having now described the rincipal parts involved in my invention I s all briefly describe its operation and utility. The rolls 0 and D are driven from a suitable source of power and as the shaft D is caused to rotate the roll D has imparted to it a longitudinal reciprocating movement as well as a rotary one, thus serving as it passes crosswise of the major roll 0 to keep the surface'thereof true as well as the surface of itself. ,In addition the rolls have a shearing action on the ore or material, which passes between the same,

thus adding materially to the efiiciency of the rolls. As the material'is fed into the hop er H such hop er it will be seen has imparted to it a longitu inal reciprocating movement on the guide rods I by means of the rollers K, thus always keeping the chute of the hopper directly over thecenter of the rolls D, which is an important vdesideratum.

, Although I show in- Figs. 1 and 2 the minor roll co-acting with .a major roll it will be understood that such minor roll may bewith equal facility adapted to co act with a stationary hollow arc-shaped trough-like block as indicated in Fig. 3. The block would be means for driving said shafts, the shaft of the minor roll extending beyond said roll at one side thereof, a cam on said extended end of the shaft, and a pair of rollers vertically j ournaledbet-ween which said cam extends and 2. Ina machine of the class described, the combination with a major roll and a minor roll held on suitable shafts journaled in suitable bearings and suitably driven, of means for mparting a longitudinal movement to .of greater length'than the roll aiid would, of

one of the rolls during rotation and a hopper supported on suitable guide ways and means for imparting movement to the hopper to follow in unison the movement of the roll as and for the purpose specified.

3. In a machine of the class described, the combination with a ma'or roll and a minor roll held on suitable shaits journaled in suitable bearings and suitably driven, of means for impartin a longitudinal movement to one of the r0 s during rotation and a hopper su ported on suitable guide Ways, or guiding r0 s secured in the frame of the machine, rollers journaled on the to of the hopper and supported on the rods an means for imparting a movement 'to the hopper to follow in unison the movement of the rolls as and for the purpose specified.

4. In a machine of the class described, the combination with a major roll and a minor roll held on suitable shafts j ournaled in suitable bearings and suitably driven, of means for impartin a longitudinal movement to one of the r01 s durinif rotation and a hopper supported on suitab e guide-wa s, or uidin rods secured in the frame of t 1e mac line, ro lers journaled on the top of the hopper and supported on the rods, pins extending downwardly from the ho per and rollers journaled on the pins and a utting one of the rolls as and for the purpose specified.
